Backend of a iOS Notification System
Mihál, Martin ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
The aim of this thesis is to design and implement backend of an iOS notification system, which can receive a notification through web request and send it to an iOS device. System sends notifications to iOS devices through the Apple notification server. System also provides a complete account management, which allows users to agregate notitifications into so-called services. These represent a user's software, which sends notifications. System communicates with the iOS application representing user through REST or GraphQL web service.

Server for Continuous Integration
Šajdík, Michal ; Fiedor, Tomáš (referee) ; Lengál, Ondřej (advisor)
Tato práce obsahuje popis následujících témat: jaké technologie a principy jsou potřebné pro vytvoření kontinuálního integračního serveru, již existující řešení, proč je potřeba jeden vytvořit a jak integrovat kontinuální integrační server, který byl vytvořen během této práce, na základě informací uvedených v této práci, do pracovního prostředí. Tato práce také ukazuje efekty a některé vedlejší účinky způsobené správnou a nesprávnou konfiguraci uvedeného serveru pro kontinuální integraci. Uvedený server pro kontinuální integraci je také schopen běžet na MS Windows 10 a Linuxu, aniž by bylo nutné přizpůsobit konfiguraci pro konkrétní operační systém.

Utilization of Linux Containers for HW/SW Co-Design
Juřica, Jiří ; Přikryl, Zdeněk (referee) ; Hruška, Tomáš (advisor)
In this bachelor thesis a way of replacement standard virtual machines by Linux containers is described. The goal is to create a~fully working system for performing parallel jobs with prepared environments for software build and test purposes. For containerization the Docker platform was chosen, which is used with automation tool for computers preparation. The system is also connected with continuous integration tool called Jenkins. This solution proves that usage of the Linux containers is more efficient than older virtualization technologies. The due time of each job was shortened about 24 % in average. The main benefits of this thesis is the comparison of two ways of virtualization and the introduction to the Docker technology.

Information System for Monitoring and Detecting Black Dumps
Chmelický, Oliver ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
This thesis covers the process of reporting black dumps and organizing it`s collection. Platform creates an evidence about these collections and saves it in a database. At the same time thesis analysis and compares existing software solutions with similar purpose. The aim of the platform is to spread an awareness among people and nature lovers. The thesis also tries to show how modern technologies can help to protect environment

Employee Attendance System
Bartošek, Jan ; Kučera, Jan (referee) ; Kocnová, Jitka (advisor)
This bachelor's thesis concerns to design and implementation of a time and attendancesystem to track the employees in the company. In the first part defines what does a timeand attendance system mean and presents both statistics data and existing systems. In thenext part aims on designing such a software able to track employees, manage vacation andexport records. Continues with a list of used technologies and implementation of the systemitself. At the end the proccess and results of testing the system are described.

Front-End for Generator of Test Data
Freyburg, Petr ; Janoušek, Vladimír (referee) ; Smrčka, Aleš (advisor)
The goal of this bachelor thesis is to create web application for generating structured test data for software testing. The project integrates existing test data generator Gestr. The project includes creating REST application interface and web frontend. The tool is implemented using Python and Flask framework, user interface is realized by HTML, CSS and JavaScript. Application can prepare inputs for generator and start generating.

Load analyser for industrial networks
Trávník, Kryštof ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
The bachelor thesis is focused on developing an application, which is consisted of a web application and a web server. In the theoretical part are described topics such as DLMS protocol, specificationCOSEM, attacks on service denial, tools for generating denial attacks, and key parts of Docker. The app which is created is sending a request to smart meters together with Denial of service attacks. Hping3 is used for generating DoS attacks and several options of attack are available. The app is created in Java. Received results are shown in form CSV and also graphically in the web application.

Industrial data collection system
Hvizdák, Lukáš ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
The master thesis focuses on the design and implementation of data collection from production using a PLC into an SQL database located in the cloud and subsequent visualization. The work describes the applicable communication protocols MQTT and OPC UA with the fact that the protocol MQTT was selected. It deals with securing data transfer from the line to the cloud using the TLS protocol. The individual cloud services and their possibilities for data collection are described here. The work deals with the possibilities of data visualization using existing open source solutions and the differences between them. I describe the possibilities of modifying the open source environment of the Grafany project. Real dashboards from production are presented. The data collection system was deployed in two plants for testing.

Application of simulation model of access network
Szymeczek, Andrzej ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The topic of the diploma thesis is " Application of simulation model of access network". The aim of the thesis was to create a part of the access network in which were tested simulations for TCP and UDP traffic. The theoretical part of the thesis deals with general information about the GNS3 program and the possibilities which this program allows. The next part of the thesis describes the Mikrotik RouterOS program, which was used in the topology. The next section describes the types of routing in IP networks, as well as the types of packet delivery. The practical part deals with the creation of test topologies and verification of the performance of the simulation tool. Furthermore, the practical part deals with the programming of a network generator for TCP and UDP traffic in the network. The generator was created by using a Bash script and a combination of the dd and nc commands. At the end, the thesis describes the results of simulations in terms of transmission speed, network throughput, packet size distribution and in the case of TCP also bidirectional delay – RTT.

Communication infrastructure virtualization platform
Stodůlka, Tomáš ; Martinásek, Zdeněk (referee) ; Uher, Václav (advisor)
The thesis deals with selection of infrastructure virtualization platform focusing on containerization with sandboxing support and with following examination of its difculty. The work begins with an explanation of the basic technologies such as: virtualization, cloud computing and containerization, along with their representatives, that mediate the technology. A special scope is defned for cloud computing platforms: Kubernetes, OpenStack and OpenShift. Futhermore, the most suitable platform is selected and deployed using own technique so that it fullflls all the conditions specifed by thesis supervisor. Within the difculty testing of the selected platform, there are created scripts (mainly in the Bash language) for scanning system load, creating scenarios, stress testing and automation.
